Summary
The PerformanceTiming
.domInteractive
read-only property returns an unsigned long long
representing the moment, in miliseconds since the UNIX epoch, when the parser finished its work on the main document, that is when its Document.readyState
changes to 'interactive'
and the corresponding readystatechange
event is thrown.
This property can be used to measure the speed of loading Web sites that users feels. Nevertheless there are a few caveats that happens if scripts are blocking rendering and not loaded asynchronously or with custom Web fonts. Check if you are in one of these cases before using this property as a proxy for the user experience of a Web site's speed of loading.
